What is API, ILSAC, and ACEA?

The owner's manual of your vehicle will usually show what API, ILSAC, and/or ACEA specifications are necessary when selecting your motor oil.

Your vehicle manufacturer is the OEM. Your owner's manual will often provide you with both Requirements (you must only use X grade) and Recommendations (we recommend brand "Y" motor oils). Always adhere to the OEM's Requirements to ensure warranty protection. 

 

For example, it may say "USE ONLY API SN/ILSAC GF-5 ENGINE OIL".

 

API is the American Petroleum Institute. They're a national trade association representing the oil and natural gas industry. From producers, refiners, suppliers, marketers, pipeline operators, marine transporters, and service and supply companies that support these segments.

ILSAC is the International Lubricant Standardization and Approval Committee. ILSAC works with API in creating the newest gasoline oil specification, with ILSAC adding an extra requirement of fuel economy testing to their specification. 

 

ACEA is the European Automobile Manufacturers Association and is the main lobbying and standards group of the automobile industry in the EU. 

 

Members include manufacturers of BMW, Mercedes, Jaguar, Land Rover, Volkswagen, Diamler AG, Fiat, Chrysler, Volvo, Alfa Romeo, Dodge, Jeep, Maserati, Toyota, and more.

 

A major area of ACEA work has been in performance classifications of engine oils.
